In this follow up to Liar's Poker, Lewis goes back to Wall Street to find out how it all came crashing down. When he gave the warning, no one listened.  Famous for his character-driven narratives, Lewis carefully outlines how it all began and how it all fell apart. He tells the story of several traders, revealing the history of the mortgage-backed security and the ever increasing complexity with which each new financial instrument was created. Each layer being based on increasingly risky mortgages originated by the big banks. A house of cards waiting to tumble. As always, Lewis puts the reader behind the scenes and is able to explain this web of complicated financial transactions for everyone to understand. Too bad we didn't heed his warning in the first place.
